What OS can I use MU4-USBIF on?

The USB chip used in the MU4-USBIF is made by FTDI Ltd., and it requires a dedicated driver. On Microsoft Windows 8 and 10, you can install the driver (included in the installation folder) and therefore use the MU4-USBIF, however you need to disable the driver signature enforcement.

Please see the application note for details.
